The vibration of hydraulic piston pumps is induced by the periodically changing cylinder chamber pressure whose waveform is significantly influenced by valve plate geometry. In this study, the force input to the housing of a bent-axis type hydraulic piston pump was computed by deriving the dynamic equations of its piston and cylinder barrel. The vibration intensity of the pump was represented by the acceleration amplitude of its housing. In order to comparatively evaluate the influence of valve plate geometry on the vibration of pump housing, two different types of valve plate were tested. The computed results showed good agreement with the experimental data, indicating that the vibration acceleration of pump housing is rather dependent on the variation amplitude of balance coefficient than the changing slope or overshoot of cylinder chamber pressure. It was also confirmed that the design effect of valve plates could be directly examined out by monitoring the vibration acceleration of pump housing.

This research starts from the questioning of current housing development situation on hilly sites in Korea. It aims to investigate various design techniques of terraced housing as an alternative housing type on sloped sites. Several generic solutions are proposed, as for site slope and stacking method, combination of dwelling units, access pattern, and sectional variation of unit space. By the comparative analysis of design proposals with the typical two-row vertical-access type, the efficiency of the proposed techniques are verified in terms of development density, provision of community space, habitability of dwelling units.

While we go through a rapid change in society, family types composing social relationship underwent lots of changes. Recently the range of family is included not only families on the basis of blood relationship but also single family, a one-parent family and non-blood relationship family. Now we need not unified types of housing but social integrated housing models responding to family diversity. The purpose of this study is that examine family diversity through social statistics and demography and grasp the current housing types responding to family diversity. The features of family diversity are reducing the number of family member and turning up a unformal family type. At the social statistics and demography in 2005, the number of family member is only 2.9 people per family. Due to decline of birth rate and change of marriage consciousness, various family types appear and increase such as single family, a one-parent family and non-blood relationship family. But there is lack of housing types responding to such family diversity. This study will be a basic research to develop social integrated housing models responding to family diversity. Housing must be sensitive to change of family type, so it responds our needs based on thorough understanding on various housing life.
